The 2-pole V series is designed for pumping sewage containing suspended solids. Thanks to its high capacity, it is used in a range of applications, including municipal sewer systems, industrial sewer systems, agriculture, and wastewater treatment plants.
Specifications
All main components are made of GG25 cast iron. Two separate mechanical seals (on the motor side in the oil chamber and on the impeller side in contact with the liquid), together with high-quality components, ensure excellent performance and product reliability.
Advantages of the V2 sewage pump
The two-pole VT sewage pump is a professional product for municipal and industrial sewer systems, as well as special pumping stations. Thanks to the large space beneath its Vortex impeller, it can easily pump raw sewage containing solid and fibrous matter. Small stones, gravel, and rubbish are no problem either. The multi-vane Vortex impeller resists clogging from wipes, strings, and kitchen waste. The water vortex that forms beneath and around the impeller means that much of the solid matter does not come into direct contact with it, so the impeller wears more slowly than channel impellers. The advantage of the radially widening channels is that solid matter entering through the inlet does not get stuck in the impeller channels, but is ejected and travels along the pump housing wall to the throat.
Control
V2 sewage pumps are primarily three-phase models, but model 65/2/152 C.346 is also available in a 230 V version. The pumps can only be controlled by an external signal. To control V2 pumps, we recommend simple controllers M121 (230 V) or M131 (400 V <=7.5 kW). For more demanding users and dual-pump pumping stations, we offer professional power and control panels with relay-contactor or microprocessor control. These can also send SMS notifications and provide online monitoring.
Installation
The most common way to install the V2 raw sewage pump is on a DUTY or type B coupling foot. Less commonly used are horizontal type A coupling feet or mobile installations on a type P stand. To lower the pump along guide rails into the pumping station tank, use slings made of stainless steel chain or stainless steel cable of suitable strength, attached to the holes in the bracket at the top of the pump. The manufacturer offers a special stainless steel handle as an accessory to ensure the pump is properly balanced during lowering. When installing the coupling foot, ensure the tank bottom beneath the pump is flat; otherwise, cavitation may occur and the hydraulic components may wear out faster.
Features
• Vortex impeller with free passage,
• Moisture sensor in the oil chamber protects the motor from water ingress if the mechanical seal behind the impeller is damaged,
• Side flange outlet allows installation on a coupling foot and easy installation of an elbow connection for a flexible hose with a clamp or quick coupling,
• Thermal protection T1-T2 built into the motor winding, for connection to a suitable control panel,
• 10 m H07RNF power cable with unterminated ends,
• Warranty and post-warranty service,
• 24-month warranty.
Special versions designed for liquid temperatures up to 60°C with the pump fully submerged are available to order (not for continuous operation).
